away, showing the application of my invention to a water column, as ahigh and as .a low water alarm, and also as a feed water regulator; Fig.2 is a view similar to Fig. 1, but showing the application of theinvention as a feed-water regulator onlyg Figs.

3 and 4 are sectional views showing the device as adapted for acombination gage cock and low water alarm, the planes of the twosections being at right angles to each other; Fig. 5 is a view similarto Fig. 3, but showing the device as adapted for a high water alarm; andFig. 6 is an end view.

My invention has relation to combination gage cocks and high and lowwater alarms, and is designed to provide a simple and eflicient deviceof this character which can be readily adapted for use either as a highor as a low water alarm.

My invention also provides a device which is capable of use asaregulator for feed water pumps, etc.

The nature of my invention will be best understood by reference to theaccompanying drawings, in which I have shown the preferred embodimentthereof, and which will now be described,'it being premised, however,that various changes can be made in the details of construction andarrangement of the several parts, without departing from the spirit andscope of the invention as defined in the appended claims.

In these drawings, the numeral 2 designates a water column, which is ingeneral of the usual character, and which is shown in Fig.1 as having athreaded boss 3 for the attachment of the high water alarm, and asimilar boss 4 for the attachment of a low water alarm.

The alarm device comprises a body 5 havtacle 8, which is designed tocontain some fluid which will expand and contract under variations intemperature. The neck portion 9 of this bulb has an opening 10communicating with the interior of the bulb and also leading into adiaphragm chamber 11 at one side of a diaphragm 12, which is held at itsperipheral edges by the bolting flange of thecap .6. Attached tov thediaphragm is a stem 13 which extends within the body 5 and carries avalve 14. This valve controls a port 15 in a diaphragm or partitionwall16 placed within a chamber 17 in said body. One end of the chamber 17 isat all times connected with the interior of the water column by a portor passage 18 which extends through the body 5 and through the cap 6.The other side of the chamber 17 communicates by a suitable pipeconnection 19 with an alarm whistle 20, in the arrangement shown in Fig.1.

The stem 13 is provided with a suitable packing 22 within the body 5,this packing has a spring 23 seated against it and against an adjustingring 24, and another spring 25 is seated between the opposite side ofthis ring and diaphragm 12.

The end cap 7 has a port 26 normally closed by a hand valve 27 andconnecting one end of the chamber 17 with a blow-ofi' 28. This blow-oft28 is shown as extending into a pipe or nozzle 29, which communicates bya port 30 with the air side of the diaphragm chamber 11.

Supposing the device to be arranged as a 'low water alarm, as in Figs. 3and 4, the

operation is as follows :As soon as the bulb 8 becomes uncovered withwater and is subjected to the action of steam in the water column, theexpansion of the liquid contained therein is suflicient to actuate thediaphragm 11 to open the valve 14, and therebyadmit steam through theport 15' and connection 19 to the alarm or whistle.

To adapt the device for'use as a high water alarm, the valve 14 isshifted on the stem 13 t0 the opposite side of the diaphragm 16, asshown in Fig. 5. In this arrangement, when the bulb 8 is covered orpartly covered with water, a contraction of the liquid contained thereinwill takev age or condensation in the air side of the diaphragm chamberwill be siphoned or drawn oft at the nozzle 29 through the port 30. V

The device as shown in Figs. 3 and 4: can be adapted for use as a feedwater regulator in the manner shown in 2. WVhen so used, a pipe 31 isattached to the connection 19, and is extended to a device for operatinga control valve in the feed water supply pipe. In so far as the presentapplication is concerned, any suitable device may be used for thispurpose. I have, however, in Fig. 2, indicated a particular form ofdevice which forms the subject-matter of a co pending application SerialNo. 688,978 filed April 6, 1912. This device is shown as consisting of acylinder 32 having a piston 33 therein below which the pipe 31 enters.The stem 34 of this piston is connected to the weighted lever 35 of acontrol valve, which is located in the casing 36 in the feed watersupply line 37. The weighted lever normally maintains its valve closed;but when the steam is admitted to the chamber 17 and thence to the pipe31, the piston 33 is actuated to open the valve and to hold it openuntil the water level in the column 2 is again restored to normal. 7

My invention may also be readily adapted to control the operation ofpump regulators and similar devices.

The advantages of the invention result from the simplicity ofconstruction; from the fact that the device can be used with little orno change for a variety of different purposes; that it is efiective andreliable in its operation; and that it can be manufactured and sold at arelatively low cost. It also does away with the use of floats andfloat-operated connections such as areusually employed in devices ofthis character, and which are open to various objections.

That I claim is 1. In a device for actuating high and low water alarmsand feed-water regulators, the combination with a water container andwith a device to be operated, of a controlling device comprising acasing having means for its attachment to the container and also havinga steam escape passage opening into the interior of the container andalso connected with the device to be operated, a valve for controllingthe passage of steam from the container through said passageway to thedevice to be operated, a, diaphragm chamber in the casing, a diaphragmin said; chamber, an actuating connection betweenthe diaphragm and thevalve, and thermostatic means carried by the casing and adapted to causethe actuation of the diaphragm; substantially as described.

2. The combination with a water container, of a casing connected theretoand containing a diaphragm chamber, a diaphragm 1n sald chamber, a valveconnected the container and having its interior communicating with thediaphragm chamber at one side of the diaphragm, the casing having a ventport leading from the opposite side of the diaphragm chamber,substantially as described. V

3. In a device for actuating high and low water alarms and feed-waterregulators, the combination with a water container and with a device tobe operated, of a controlling device comprising a casing having. meansfor its attachment to the container and also having a steam escapepassage opening into the interior of the container and also connectedwith the device to be operated, a valve for controlling the passage ofsteam from the container through said passageway to the device to beoperated, a diaphragm chamber in the casing, a diaphragm in saidchamber, an actuating connection between the diaphragm and the valve,and a bulblike receptacle connected to the casing and projecting withinthe container, the space within said receptacle communicating with thediaphragm chamber and being designed to be filled with an expansiblefluid; substantially as described.

4. The combination with a water container, of a device for indicating orcontrolling the water level in said container, said device comprising acasing having means for its attachment to the container, the casing alsohaving a steam passage leading therethrough from the interior of thecontainer and communicating directly with the interior of the containerat one end, a valve for controlling said passage, a device connected tothe outlet end of said passage to be operated by the steam escapingtherethrough when the said valve is opened, and means controlled by thewater level in the container for actuating the valve, substantially asdescribed. a

5. The combination with a water container, of a device for indicating orcontrolling the water level in said container, said device comprising acasing having means for its attachment to the container, the casing alsohaving a steam passage lead the casing for actuating the diaphragm, sub-10 stantially as described.

In testimony whereof, I have hereunto set ing therethrough from theinterior of the container and communicating directly with the interiorof the container at one end, a

valve for controlling said passage, a device my hand.

connected to the outlet end of said passage to be operated by the steamescaping there- WERNER STAAF' through when the said valve is opened, aWitnesses:
